Data Structures Algorithms Online Quiz
Following quiz provides Multiple Choice Questions (MCQs) related to Data Structures Algorithms. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.
Q 1 - A procedure that calls itself is called
Answer : C
Explanation
In recursion, a procedure calls itself, either directly or by calling a procedure which in turn calls it.
Answer : B
Explanation
Expression notations are not reverse (or so) of each other, rather operators used in the expression have different arrangements.
Q 3 - Quick sort algorithm is an example of
Answer : D
Explanation
Quick sort divides the list using pivot and then sorts in recursive manner. It uses divide and conquer approach.
Q 4 - Which of the following algorithm is not stable?
Answer : B
Explanation
Among the given, only quick sort is not stable that is it may re-arrange the already sorted items.
Q 5 - After each iteration in bubble sort
A - at least one element is at its sorted position.
Answer : A
Explanation
In one iteration of Bubble sort, the maximum of the set in hand is moved at the end of the unsorted list. Hence one less comparison.
Q 6 - Which of the below mentioned sorting algorithms are not stable?
Answer : A
Explanation
Except selection sort, all other soring algorithms are stable.
Q 7 - Index of arrays in C programming langauge starts from
Answer : A
Explanation
Arrays, in C, starts from 0 which is mapped to its base address.
Q 8 - All possible spanning trees of graph G
A - have same number of edges and vertices.
B - have same number of edges and but not vertices.
Answer : A
Explanation
All possible spanning trees of graph G, have same number of edges and vertices.
Answer : A
Explanation
Shell sort uses insertion sort when interval value is 1.
Q 10 - Interpolation search is an improved variant of binary search. It is necessary for this search algorithm to work that −
A - data collection should be in sorted form and equally distributed.
B - data collection should be in sorted form and but not equally distributed.
C - data collection should be equally distributed but not sorted.
Answer : A
Explanation
For this algorithm to work properly the data collection should be in sorted form and equally distributed.
